- Eating disorders and substance use disorders frequently co-occur. Twin studies reveal shared genetic variance between liabilities to eating disorders and substance use, with the strongest associations between symptoms of bulimia nervosa and problem alcohol use (genetic correlation [r(g)], twin-based = 0.23-0.53). We estimated the genetic correlation between eating disorder and substance use and disorder phenotypes using data from genome-wide association studies (GWAS). Four eating disorder phenotypes (anorexia nervosa [AN], AN with binge eating, AN without binge eating, and a bulimia nervosa factor score), and eight substance-use-related phenotypes (drinks per week, alcohol use disorder [AUD], smoking initiation, current smoking, cigarettes per day, nicotine dependence, cannabis initiation, and cannabis use disorder) from eight studies were included. Significant genetic correlations were adjusted for variants associated with major depressive disorder and schizophrenia. Total study sample sizes per phenotype ranged from similar to 2400 to similar to 537 000 individuals. We used linkage disequilibrium score regression to calculate single nucleotide polymorphism-based genetic correlations between eating disorder- and substance-use-related phenotypes. Significant positive genetic associations emerged between AUD and AN (r(g) = 0.18; false discovery rate q = 0.0006), cannabis initiation and AN (r(g) = 0.23; q < 0.0001), and cannabis initiation and AN with binge eating (r(g) = 0.27; q = 0.0016). Conversely, significant negative genetic correlations were observed between three nondiagnostic smoking phenotypes (smoking initiation, current smoking, and cigarettes per day) and AN without binge eating (r(gs) = -0.19 to -0.23; qs < 0.04). The genetic correlation between AUD and AN was no longer significant after co-varying for major depressive disorder loci. The patterns of association between eating disorder- and substance-use-related phenotypes highlights the potentially complex and substance-specific relationships among these behaviors.

- The disposition of Na2B12H11SH (BSH) in patients with malignant glioma has been investigated, in preparation for a Phase I clinical trial of boron neutron capture therapy. BSH was found to possess a linear disposition over the dosage interval investigated (up to 75 mg/kg). A bi-phasic blood pharmacokinetics was observed. Tumour-to-blood ratios showed variations between patients between 0.08 and 5.1. The data allow the definition of amount of BSH and timing of infusion for a Phase I clinical trial protocol.

- Background: While numerous interventions effectively interfered with abdominal aortic aneurysm (AAA) formation/progression in preclinical models, none of the successes translated into clinical success. Hence, a systematic exploration of parallel and divergent processes in clinical AAA disease and its 2 primary models (the porcine pancreatic elastase and angiotensin-II infusion [AngII] murine model) was performed to identify mechanisms relevant for aneurysm disease.Methods and Results: This study combines Movat staining and pathway analysis for histological and genomic comparisons between clinical disease and its models. The impact of a notable genomic signal for metabolic reprogramming was tested in a rescue trial (AngII model) evaluating the impact of 1-(4-pyridinyl)-3-(2-quinolinyl)-2-propen-1-one (PFK15)-mediated interference with main glycolytic switch PFKFB3. Histological evaluation characterized the AngII model as a dissection model that is accompanied by adventitial fibrosis. The porcine pancreatic elastase model showed a transient inflammatory response and aortic dilatation, followed by stabilization and fibrosis. Normalization of the genomic responses at day 14 confirmed the self-limiting nature of the porcine pancreatic elastase model. Clear parallel genomic responses with activated adaptive immune responses, and particularly strong signals for metabolic switching were observed in human AAA and the AngII model. Rescue intervention with the glycolysis inhibitor PFK15 in the AngII model showed that interference with the glycolytic switching quenches aneurysm formation.Conclusions: Despite clear morphological contrasts, remarkable genomic parallels exist for clinical AAA disease and the AngII model. The metabolic response appears causatively involved in AAA progression and provides a novel therapeutic target. The clear transient genomic response classifies the porcine pancreatic elastase model as a disease initiation model.

- This report described an interim analysis of a investigator-driven multicenter trial in renal transplant recipients: the Prospective Quality of life Renal Transplantation Switch Study; Tacrolimus-based immunosuppression ("PQRST study"). Patients included in the trial initially treated with cyclosporine-based immunosuppression after renal transplantation who experienced side effects, such as hypertension, hyperlipidemia, hypertrichosis, or other adverse reactions, were converted to a tacrolimus-based immunosuppressive regimen (n = 31). Steroids were subsequently discontinued between 3 and 6 months after the conversion. As of today 19/31 (50%) patients have been successfully weaned off steroids with the remaining patients in this process. In this interim analysis, with a follow-up ranging from 1 to 18 months both patient and graft survivals were 100%. No patient experienced an acute rejection episode; none of the grafts were lost. Blood pressure decreased in 22/31 (71%) of the patients. No patient developed de novo diabetes or other serious side effect related to the conversion. Three patients were withdrawn from the trial because of side effects: bleeding, depression, and proteinuria. However, none of these adverse events were felt to be directly related to the change of the immunosuppressive regimen to tacrolimus monotherapy. In conclusion, conversion from cyclosporine to tacrolimus-based therapy was safe and well tolerated; it may improve the cardiovascular risk profile after kidney transplantation.
